Description

Technical Field

[0001] This utility model belongs to the field of PCB board processing technology, and in particular relates to a corner rounding machine for PCB board production and processing. Background Technology

[0002] In the current era of rapid development in the electronic information industry, PCB boards, as the core carriers for carrying electronic components and realizing circuit connections, have been widely used in many fields such as smartphones, computers, communication equipment, automotive electronics, and industrial control. As electronic products iterate towards miniaturization, lightweighting, and high integration, the processing accuracy and edge quality of PCB boards have become increasingly critical to subsequent assembly efficiency and product reliability. Rounding corner processing is an important process in the PCB board production process to ensure edge quality.

[0003] For example, Chinese Patent (Publication No.: CN220762855U) discloses a corner rounding machine for PCB board production and processing, including a support base box, a support platform on the top of the support base box, a limit box on the top of the support platform, and a first support vertical plate on the side of the top of the support platform corresponding to the position of the limit box. This utility model improves the convenience of board removal by using a board strip, increases the fixing area by using a cross-shaped fixing component to prevent displacement due to vibration during PCB board cutting, and improves the stability of the fixing. The sandpaper on the side of the sanding plate polishes the rounded corners of the PCB board, improving the quality of the finished PCB board. Scrap from the PCB board and sanding debris falls through a chip hole into a chip collection drawer. Finally, personnel can pull the chip collection drawer out of the support base box using a grip to process the scrap and debris, improving chip collection efficiency. However, during use, chip collection... The passive structure that relies on the natural fall of chips through the chip vent and the chip collection drawer for collection is prone to problems. Lightweight particles such as glass fiber shavings and resin powder generated during the grinding process easily escape from the gravity collection range and fly around, seriously polluting the working environment and potentially being inhaled by operators, which is harmful to their health. More importantly, the flying debris can easily enter the transmission gaps, bearing connections, and other narrow parts of the equipment. Long-term accumulation can lead to transmission jamming and accelerated wear of components. This not only affects the accuracy and stability of corner rounding but also shortens the service life of the equipment and increases maintenance costs and downtime. Therefore, a corner rounding machine for PCB board production and processing is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a corner rounding machine for PCB board production and processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A corner rounding machine for PCB board production and processing includes a base, an L-shaped support rod welded to the top of the base, a grinding component connected to one corner of the base, a support seat connected to the top middle of the base, a first motor connected inside the support seat, and a placement frame connected to the output end of the first motor via a connecting shaft.

[0007] The polishing assembly includes a vacuum cleaner, the vacuum cleaner's suction port is connected to a corrugated pipe, one end of the corrugated pipe is connected to a connecting pipe, one end of the connecting pipe is connected to a flow guide, the bottom of the connecting pipe is connected to a connecting rod, one end of the connecting rod is connected to a protective box, the inside of the protective box is connected to a second motor, the output end of the second motor is connected to a rotating component, one end of the rotating component is connected to an arc-shaped polishing plate, and the bottom of the rotating component is connected to a second hydraulic telescopic rod.

[0008] In a further technical solution, one end of the second hydraulic telescopic rod is rotatably connected to the bottom of the rotating component, the interior of the guide shroud is funnel-shaped, and the guide shroud is located diagonally above the arc-shaped grinding plate.

[0009] In a further technical solution, the second motor is a dual-shaft motor, and the other output end of the second motor is connected to the connecting rod.

[0010] In a further technical solution, the output end of the first motor is connected to an angle sensor via a connecting shaft. The angle sensor is located inside the support base, and the bottom of the second hydraulic telescopic rod is connected to the top of the vacuum cleaner.

[0011] In a further technical solution, there are two L-shaped support rods, one of which has a stamping cylinder connected through one end, a connector connected to one end of the stamping cylinder, and an arc-shaped cutter connected to one end of the connector.

[0012] In a further technical solution, one end of the other L-shaped support rod is connected to a first hydraulic telescopic rod, and one end of the first hydraulic telescopic rod is connected to a cross-shaped fixing member, which is located above the placement frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves starting a vacuum cleaner, which forms an active debris collection system through a corrugated pipe, connecting pipe, and a horn-shaped guide hood. The guide hood is located diagonally above the arc-shaped grinding plate, precisely covering the grinding area and efficiently capturing lightweight particles such as glass fiber debris and resin powder generated during grinding. This avoids the debris flying problem caused by traditional passive collection. This not only keeps the processing area clean and prevents debris from contaminating the working environment, but also prevents operators from inhaling harmful particles, effectively protecting their health. At the same time, it prevents debris from entering the transmission gaps and bearing connections of the equipment, reducing equipment jamming and component wear, and lowering maintenance costs and downtime.

[0015] This invention features a first motor inside the support base that drives the placement frame to rotate via a connecting shaft. An angle sensor monitors the rotation angle of the placement frame in real time, allowing for precise control of the PCB board's rotation position. This enables the equipment to automatically rotate to the grinding assembly for grinding after cutting, eliminating the need for the user to remove the PCB board for adjustment, greatly simplifying operation. In the grinding assembly, a second motor drives the rotating component and the arc-shaped grinding plate to rotate, achieving the grinding action. Simultaneously, it drives the connecting rod to synchronously adjust the position of the connecting pipe and the guide shield, ensuring the guide shield always precisely aligns with the grinding area. Furthermore, the second hydraulic telescopic rod can flexibly adjust the height of the rotating component and the arc-shaped grinding plate to accommodate grinding requirements of PCB boards of varying thicknesses. This multi-layered precision control structure effectively avoids the angle deviation and uneven grinding problems inherent in traditional equipment, significantly improving the accuracy of PCB board corner processing and the consistency of the finished product.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] The polishing assembly 3 includes a vacuum cleaner 301, the vacuum cleaner 301 has a vacuum port connected to a corrugated pipe 302, one end of the corrugated pipe 302 is connected to a connecting pipe 303, one end of the connecting pipe 303 is connected to a flow guide shroud 304, the bottom of the connecting pipe 303 is connected to a connecting rod 305, one end of the connecting rod 305 is connected to a protective box 306, the inside of the protective box 306 is connected to a second motor 307, the output end of the second motor 307 is connected to a rotating component 308, one end of the rotating component 308 is connected to an arc-shaped polishing plate 309, and the bottom of the rotating component 308 is connected to a second hydraulic telescopic rod 310.

[0025] In this embodiment, the vacuum cleaner 301 is activated. The vacuum cleaner 301 forms an active debris collection system with the corrugated pipe 302, connecting pipe 303, and horn-shaped guide hood 304. The guide hood 304 is located diagonally above the arc-shaped grinding plate 309, which can accurately target the grinding area and efficiently capture lightweight particles such as glass fiber debris and resin powder generated during grinding, thereby avoiding the debris flying problem caused by traditional passive collection. By activating the second motor 307, the arc-shaped grinding plate 309 can be rotated to grind the PCB board. At the same time, the guide hood 304 rotates with the arc-shaped grinding plate 309, so that the guide hood 304 is always above the grinding plate, which facilitates precise dust suction and prevents dust generated during grinding from flying and affecting the use of the equipment. The position of the arc-shaped grinding plate 309 can be adjusted by the second hydraulic telescopic rod 310, so that the equipment can adapt to PCB boards of different thicknesses and improve the applicability of the equipment.

[0026] like Figure 2 and Figure 3As shown, specifically, one end of the second hydraulic telescopic rod 310 is rotatably connected to the bottom of the rotating part 308, the inside of the guide shield 304 is trumpet-shaped, and the guide shield 304 is located diagonally above the arc-shaped grinding plate 309.

[0027] The second motor 307 is a dual-output shaft motor, and the other output end of the second motor 307 is connected to the connecting rod 305.

[0028] The output end of the first motor 5 is connected to an angle sensor 12 via a connecting shaft. The angle sensor 12 is located inside the support base 4. The bottom of the second hydraulic telescopic rod 310 is connected to the top of the vacuum cleaner 301.

[0029] There are two L-shaped support rods 2. One end of one L-shaped support rod 2 is connected to a stamping cylinder 9. One end of the stamping cylinder 9 is connected to a connector 10. One end of the connector 10 is connected to an arc-shaped cutter 11.

The stamping cylinder 9 is activated to drive the arc-shaped cutter 11 to cut the PCB board. The first motor 5 inside the support base 4 drives the placement frame 6 to rotate through the connecting shaft. With the help of the angle sensor 12 to monitor the rotation angle of the placement frame 6 in real time, the rotation position of the PCB board can be precisely controlled, ensuring that the angle of each rounded corner processing is accurate and controllable. After the cutting is completed, the equipment can automatically rotate to the grinding component 3 for grinding, without the need for the user to remove the PCB board to adjust its position, which greatly facilitates the user's use.

[0032] The working principle of this utility model is as follows: First, the PCB board to be processed is placed in the placement frame 6. The first hydraulic telescopic rod 7 is activated to drive the cross-shaped fixing part 8 to move down, thereby fixing the PCB board. The stamping cylinder 9 is activated to drive the arc-shaped cutter 11 to cut the PCB board. Then, the first motor 5 inside the support base 4 drives the placement frame 6 to rotate through the connecting shaft. With the help of the angle sensor 12 to monitor the rotation angle of the placement frame 6 in real time, the rotation position of the PCB board can be precisely controlled to ensure that the angle of each rounded corner processing is accurate and controllable. After the cutting is completed, the equipment can rotate to the grinding component 3 by itself. Finally, the vacuum cleaner 301 is activated. The vacuum cleaner 301 forms an active debris collection system through the corrugated pipe 302, the connecting pipe 303 and the horn-shaped guide hood 304. The guide hood 304 is located diagonally above the arc-shaped grinding plate 309, which can accurately aim at the grinding area and efficiently capture the light particles such as glass fiber debris and resin powder generated during grinding, thereby avoiding the debris flying problem caused by traditional passive collection.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
